What is the Difference Between Effluent and Sewage treatment plant?

January 14, 2023by newebay020

Based on where it comes from, waste water may be divided into two major groups. They include industrial wastewater and sewage treatment plant. Industrial effluent is wastewater produced by different industries, whereas sewage is wastewater produced by residential areas like communities.

The basic difference between the effluent and the sewage treatment plant lies at origin or source of generation. Here we are going to know about the differences clearly….

What is Effluent?

Sewage treatment plant that has been cleaned up in a sewage treatment facility or septic tank is called effluent. It is also known as “wastewater” or “trade effluent.” Effluent is waste that is not surface water, residential sewage, kitchen or bathroom trash. Any industrial or commercial facility is capable of producing and discharging it. Effluent typically drains from the property directly into the main sewer network, and it must be cleaned and treated before it can enter a river, stream, reservoir, or lake.

Typically, effluent comprises one or more pollutants, such as:

  • Chemicals, oils, Fats, and greases (FOGs)
  • Solids, food waste, heavy metal rinses, and detergents

Strict regulatory standards must be met by industrial effluent released from processing and manufacturing facilities. These regulations are intended to safeguard groundwater and surface water resources. The following six issues will affect wastewater treatment in the future:

  • Reduced operating costs,
  • Increased efficiency through optimization,
  • Stricter environmental restrictions,
  • Water shortages and the push for reuse,
  • Evolving technology, and subproduct recovery.

Sludge is a byproduct of many facilities’ effluent treatment plant that, if properly dewatered, may be utilised as a soil component to fertiliser.

What is sewage?

The tainted water from residences, workplaces, and educational institutions is referred to as sewage. It comes from things like showers, toilets, washing machines, and dishwashers. Feces, soaps, urine, detergents, food particles, rags, hair, paper, toys, dead goldfish, and anything else thrown down down a drain are examples of pollutants. An individual produces 60 to 100 litres of wastewater on average per day. A system of pipes known as sewers transports sewage to a treatment facility for cleaning. The ongoing process of treating wastewater involves eliminating impurities and processing those contaminants into a product that can be recycled safely.

Based on where it comes from, waste water may be divided into two major groups. They include industrial wastewater and sewage. Industrial effluent is wastewater produced by different industries, whereas sewage is wastewater produced by residential areas like communities.

The main distinctions between effluent and sewage are:

Domestic wastewater produced by a community of people is referred to as sewage.



This is the waste that any industrial or commercial process dumped into our sewers.
The many drains and pipelines in the neighbourhood carry sewage.


Compared to the rubbish we generate on a daily basis; this is completely different.


This is a concoction of hazardous chemicals.


This can be described as anything that isn’t part of our regular waste stream, such as bathroom waste or other trash.


Usually, sewage consists of water and waste. Sewage refers to the pipe system that carries sewage. It becomes an influent when it reaches the neighbourhood treatment system. It is once more an effluent after being treated and exiting the treatment plant.


Not all wastewater is wastewater, but all sewage is wastewater. Wastewater is water that has been used for its intended use. It can be sewage or grey water in a house. Wastewater from a particular industry might be polluted with alkalis, acids, or oils. The sewage from that facility might or might not go in the same location. Often, pretreatment or treatment is necessary for industrial wastewater.
